语音录放模块由语音录放芯片ISD2560及其外围电路组成。



1、模块上P/-R、PD 、CA0插孔分别接至实验箱的K1、K2、K3，EOM接实验箱指示灯L1，CE接单脉冲P-。

2、将K1、K3拨至低电平，K2先高后低。按一下单脉冲P-， L1应熄灭。此时对这麦克风说一段话，然后再按P-，此时L1应被点亮，录音完成。

3、将K1拨至高电平，K3拨至低电平，K2先高后低。按一下单脉冲P-， L1应熄灭，此时可以听到刚才录的语音片断。播放完成后，L1应被点亮。

1, the module P /-R, PD, CA0 jack connected to the experimental box K1, K2, K3, EOM is then the experimental tank light L1, the P-CE pulse orders.

2, K1, K3, allocated to low, K2 first high to low. Click the single pulse of the P-L1 should be extinguished. At this point this microphone passage, and then the P-L1 should be lit, recording completed.

3, K1 allocated to high, K3 allocated to low, after the K2 first low. Click the single pulse of the P-L1 should be extinguished, just recorded voice clips can be heard. Playback is complete, L1 should be lit.
